Abstract

Abstract: The kinetics of methanol dehydration to dimethyl ether (DME) over zeolite Y was studied in an integral reactor under atmospheric pressure. Based on the reaction mechanism of DME produced from methanol dehydration, four kinetic equations are obtained according to the Langmuir–Rideal (Rideal–Eley) mechanism and Langmuir-Hinshelwood mechanism. A six-parameter kinetic model of methanol dehydration to dimethyl ether over zeolite Y is obtained by data processing, and the calculated values are in good agreement with the test data.

Key words: zeolite, methanol, dimethyl ether, kinetics
